NCERT Solutions Class 8 Maths Chapter 5 Squares and square Roots Exercise 5.3

NCERT Solutions Class 8 Maths: Chapter 5 - Squares and Square Roots (Exercise 5.3)

In this exercise, students delve deeper into the concept of square roots, reinforcing their understanding of perfect squares and how to compute square roots through various methods.

Key Concepts Covered:

Definition of Square and Square Root:
- A square of a number is the result of multiplying the number by itself (e.g., $4^{2} = 16$
  
  ).
- The square root is the inverse operation, finding a number that when squared gives the original number (e.g., $\sqrt{16} =$
  
  $4$ ).
Identifying Perfect Squares:
- Students learn to identify numbers that are perfect squares (e.g., 1, 4, 9, 16, etc.) and understand the patterns in their formation.
Calculating Square Roots:
- Methods for finding square roots, including prime factorization and the long division method, are explored in detail.

Exercise 5.3 Breakdown:

Problem Solving: The exercise consists of problems requiring students to calculate the square roots of given numbers.
Application of Concepts: Students apply their knowledge to solve problems that include both perfect squares and non-perfect squares, enhancing their analytical skills.

Example Problem:

Find the square root of 64:
- Since $8 \times 8 = 64$
  
  , the square root of 64 is 8.

Tips for Success:

Practice Regularly: Regular practice helps reinforce concepts and improves problem-solving speed.
Visual Aids: Using number lines or graphs can help visualize squares and their roots.
Work in Groups: Collaborating with peers can provide different perspectives and enhance understanding.
